I must be looking wrong on this but I can't find the trick:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<script src="http://code.jquery.com/jquery-1.4.2.min.js" type="text/javascript"></script>
<script src="http://www.listinventory.com/js/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script type="text/javascript" src="http://code.google.com/p/jquery-utils/source/browse/trunk/src/jquery.countdown.js"></script>
<script type="text/javascript">
$(function hello() {
// function that does something exciting?
var liftOff = function () {
// ....
};
// Get a date that is some (short) time in the future
var getDeadline = function () {
var shortly = new Date();
shortly.setSeconds(shortly.getSeconds() + 5.5);
return shortly;
};
// Attach click handler to all our buttons
$("div.mainpanel button.resetButton").click(function (event) {
// I am assuming that you will not be nesting these controls?
var $mainpanel = $(this).parents("div.mainpanel") // this will find the mainpanel div that contains the pressed button
.effect("highlight", {}, 700);
$("div.shortly", $mainpanel) // this will find any div with the class = shortly inside mainpanel
.countdown('change', { until: getDeadline() });
});
// Start all countdowns going on page load
$('#shortly').countdown({
until: getDeadline(),
onExpiry: liftOff,
layout: '{sn}'
});
});
</script>
<div class="mainpanel">
<div>
test
</div>
<div class="shortly">
</div>
<button class="resetButton">
Reset
</button>
</div>
</asp:Content>
I get an "Microsoft JScript runtime error: Object doesn't support this property or method" exception in the countdown.
You could try to drop the "hello" from $(function hello() {
It is not necessary.
Where is the code for the countdown method? is this in a JQuery plugin or is it a function of your own?
Is it possible the naming of $mainpanel is conflicting with something else? Try renaming this to another name (without the $).
I think it must be how you reference your plug-in code. I pasted the code in-line and it works without and error.

for SEO reasons I try to descent js to footer in a big website make with prototype and jquery.
I try to encapsulate the jquery and prototype propertyes in the body to run after in footer I keep the variables and functions to make interactions.
with jquery works fine but i have problems with prototype.
here the idea in psedocode
<html>
<head>
<script type="text/javascript">
var domReadyQueue = []; // this var encapsule all js in the page
</script>
</head>
<body>
some Div and other tricks
<script type="text/javascript">
//<![CDATA[
domReadyQueue.push(function ($) {
new RegionUpdater('country', 'region', 'region_id', <?php echo $this->helper('directory')->getRegionJson() ?>);
})
//]]>
</script>
some Div and other tricks
<script type="text/javascript">
//<![CDATA[
var loginForm;
domReadyQueue.push(function($){
loginForm = new VarienForm('login-form', true);
$('login-email').observe('keypress', bindLoginPost); //here is the error
$('login-password').observe('keypress', bindLoginPost);
})
function bindLoginPost(evt){
if (evt.keyCode == Event.KEY_RETURN) {
loginForm.submit();
}
}
function onepageLogin(button)
{
if(loginForm.validator && loginForm.validator.validate()){
button.disabled = true;
loginForm.submit();

domReadyQueue.shift()(jQuery);

in console the error say
console error Uncaught TypeError: $(...).observe is not a function
exist a way to call prototype code with jquery?
exist a way in prototype to encapsulate? i can use this var to jquery and use other to prototype.
Maybe another idea to put jquery anf prototype in the footer? with a less impact in the rest of code?
the website have millons of lines, and works, change or re-thinks all is very complicate.
I have somehow a beginner's question about the following structure:
<body>
<p id="text_object">Some text</p>
<button id="button_change_text">change text on click</button>
// Individual script on page template
// ----------------------------------
<script type="text/javascript">
var object = $('#text_object');
changeTextOnLoad(object);
</script>
// Footer from included footer.php with universal main.js file
// ------------------------------------------------------------
<footer>
<script type="text/javascript" src="main.js">
</footer>
</body>
My main.js contains the following:
// declaration of function for writing new text into text object on load
function changeTextOnLoad(object) {
object.text('New text');
}
// declaration of click function
$('#button_change_text').on('click', function() {
$('#text_object').text('New text');
});
My problem: My console tells me that changeTextOnLoad() is undefined. But clicking on the button and changing the text by this way works perfectly fine. Where is the reason? Why in my main.js file does the click function get fired but not the changeTextOnLoad function?
You are calling your changeTextOnLoad function before the main.js file has loaded. Either put the function call in an onload event callback or put the include above the call
window.onload = function(){
var object = $('#text_object');
changeTextOnLoad(object);
};
//Or using addEventListener
window.addEventListener("load",function(){
var object = $('#text_object');
changeTextOnLoad(object);
});
//Or since you are using jQuery
$(document).ready(function(){
var object = $('#text_object');
changeTextOnLoad(object);
});
//Or
$(function(){
var object = $('#text_object');
changeTextOnLoad(object);
});
OR
<script type="text/javascript" src="main.js"></script>
<script type="text/javascript">
var object = $('#text_object');
changeTextOnLoad(object);
</script>
because main.js is another file, browser takes time to download it. But you run changeTextOnLoad(object); before that.
I have the following code at the end of one of my Views:
#section Scripts {
<script type="text/JavaScript">
$(document).ready(function () {
alert("!!!");
});
</script>
}
What ever I do, I can't get it to fire. I have checked and further up in the code JQuery is included. Using the suggestion here I changed my code to the following to confirm that jquery was correctly loaded. This gives the 'Yeah!' alert when loading the page.
#section Scripts {
<script type="text/JavaScript">
window.onload = function () {
if (window.jQuery) {
// jQuery is loaded
alert("Yeah!");
} else {
// jQuery is not loaded
alert("Doesn't Work");
}
}
</script>
}
The end of the source in my page looks like:

<script src="/Scripts/jquery-ui-1.8.24.js"></script>

I can't work out where I am going wrong...
if this coode works properly
window.onload = function () {
if (window.jQuery) {
// jQuery is loaded
alert("Yeah!");
} else {
// jQuery is not loaded
alert("Doesn't Work");
}
}
and this code doesn't :
$(document).ready(function () {
alert("!!!");
});
your likely problem is that there is a conflict with the dollar sign $
I would type out jQuery instead of using the dollar sign , or of course you can do something like this:
var j = jQuery.noConflict();
then you can do use the j where you used to use $
OR... there is simply just an error in the console that you still have not responded about , if that is the case I will update answer
EDIT::
The reasons that you code was not executing was because javascript is weird in the sense that if there is an error anywhere in the block of javascript code then nothing below it will be executed. That is why I asked if there were any console error's. Checking the console is the first step to solving any javascript error.
remove #section Scripts block put script block only and try... if not then remove all js use only jquery and try it will definatly. now add one by one script and find one which is conflicting. .
I've created links to transition yet when the function is supposed to be called using the onmousedown event I get an uncaught undefined function. Clearly my function is defined. I'm am still learning code so what is it I don't see or understand. Any tips will be greatly appreciated.
<html>
<head>
<script type="text/javascript"src="js/jquery.js"></script>
<script type="text/javascript" src="js/jquery-ui.js"></script>
<script type="javascript">
$(document).ready(function (){
var url = "phpajaxtut.php";
});
function swapContent(cv){
$("#myDiv").html("animated gif goes here").show();
.post(url, {contentVar:cv}, function(data){
$("#myDiv").html(data).show();
});

Why not just use $.click(); instead, since you're already using jQuery, and forgo the hyperlinks? You can easily style some spans to look like as if that's what you want. My example just updates some text, but in there you can place / call your function.
See here:
// html
<span>Click Me</span>
<br />
<span>Click Me</span>
// js
var n = 0;
$("span").click(function(){
$(this).text($(this).text() + " " + n++);
});
Do you need a $ before .post?
$.post(url, {contentVar:cv}, function(data){
$(document).ready(function (){
var url = "phpajaxtut.php";
});
The var url isn't global. It can only be used inside the function
var url; //global url
$(document).ready(function (){
url = "phpajaxtut.php"; // set global url
});
I need to handle 'tweet' event. That is what I have now, but it doesn't work:
<script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script>
<script type="text/javascript">
function jsTweet() {
// some other stuf here
// ...
var urlTW = "https://twitter.com/intent/tweet?text=Text&url=http://my_url.com";
var winTW = window.open(urlTW,'','toolbar=0, status=0, width=650, height=360');
}
(function() {
twttr.events.bind('tweet', function(event) {
alert('tweet!!!!');
});
}());
</script>
<a href="javascript:void(0)" onClick="jsTweet();">
Several things :
1/ Close your anchor tag.
2/ Your anonymous function is called only when the page is loaded. The twttr object doesn't exist at this time. So there is no binding done. Debug your function with Firebug or something, this should appear as an error.
